header.php in a child theme: Call to undefined function generate_do_attr()

Hi,
I have copied header.php from the template into the child theme folder and now I am getting this problem:
Error thrown
Call to undefined function generate_do_attr()How to solve it?
Hi there,
what changes are you wanting to make the header.php ? As you may not need to make a copy of it. Let me know.
I think I found a problem. We do use BETA versions on wp-dev instances where the theme is 3.1-beta and production is currently on 3.0.4 . Someone has changed the names of functions.
from 3.0.4:
generate_do_element_classes( 'page' );
to 3.1:
generate_do_attr( 'page' );
bit incompatibility when having child themes - and possibly require updating all of them manually after 3.1 will be released.
Hi there,
It's not required to update your child themes with the new generate_do_attr() function, it will continue to work with generate_do_element_classes().
If you do update your child themes to use this new function, you need to make sure 3.1 is installed so the new generate_do_attr() function exists.
So if you're using 3.0.4, stick with generate_do_element_classes().
Once you update to 3.1.0, you can choose to switch to generate_do_attr() whenever is convenient for you.
